A Porotherm clay block home will give you the very best of European building precision and innovation, offering everything your home should be. The walls in your Porotherm home are 100% natural clay, with absolutely no synthetic or toxic materials and substances used either in the manufacturing process or the end product. As a result, there is no toxicity present and no VOCs (Volatile Organic Compounds) outgassing over time, as occurs with timber frame construction.
Porotherm is a breathable walling system – the clay blocks, natural lime plaster and mineral paint finish creates air movement at a microscopic level, ensuring a dry and fresh indoor environment and an accompanying air quality all-year-round.
With a block thickness of 250mm and R-values* between 1.7 – 5.4, the thermal mass in the walls of your Porotherm home provides warmth in winter and cooling in summer to create an all-year-round living temperature of between 18-22C. With low energy & maintenance requirement and an economic and fast building time and cost per m2, Porotherm competes equally with high-end timber frame construction. It truly is ‘one wall does it all’.
